Preparing for Closest Approach to Phobos (IMAGE) European Space Agency Caption On July 23, 2008, the High Resolution Stereo Camera on board the ESA's Mars Express took the highest-resolution full-disc image yet of the surface of the moon Phobos. The image data was acquired from a distance of 97 km with a spatial resolution of about 3.7 m/pixel in orbit 5851. These images have surpassed all previous images from other missions in continuous coverage of the illuminated surface at the highest spatial resolution of 3.7 m/pixel. This image is photometrically enhanced to bring out the features in the less illuminated part. Credit ESA/ DLR/ FU Berlin (G. Neukum) Usage Restrictions For non-commercial use only.
